G(x) = 3x^2 - 33x -180 what are the missing portions of th function (the zeros)?

Hello from MrBillDoesMath!

x = 15 or x = -4

Discussion:

Start by factoring the given quadratic:

3x^2 - 33x - 180  =                          (factor 3 from each term)

3( x^2 - 11x - 60) =                           ( -15 + 4 = -11;  (-15)*4 = -60)

3 (x -15)(x+4)  

This equals zero when x = 15 or x = -4

Thank you,

MrB

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
